Abstract
The present invention relates to a flame retardant thermoplastic resin composition that comprises a polycarbonate resin, a rubber modified styrene-grafted copolymer, a styrene-containing copolymer, a (meth)acrylic acid ester copolymer, a phosphoric acid ester as a flame retardant and a fluorinated polyolefin resin, which does not show coalescence of the domain resin that might be caused by the low viscosity at a high temperature, and poor flame retardancy, weld-line strength and mechanical properties such as impact strength, and which has a good balance of physical properties such as impact strength, heat resistance, heat stability, processability and appearance.
